Application filed September 15, 1921. Serial No. 500,726.

To all whom t may coacewt: l,

Be it known that l., HERMANN NEUMANN, a citizen of the United States,residing at Blackwell, in the county ot Forest and State of Wisconsin,have invented certain new and useful Improvements in Car-LockingDevices; and I do declare the following to be a iiull, cle-ar, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same. n f

This invention relates to an improved device which is especially, butnot necessarily, designed for anchoring cars tothe rails on inclines sothat-in case lthe brakes tail to hold, there will be no chance or thecar running away. l

vThe principal object of the invention is to generally improve upondevices ot' this class by providing one of extreme simplicity anddurability which is mere-ly composed of an arm which is attached to thecar or other wheeled support, a pair of rail-engaging jaws which arecarried by this arm, a handoperated locking lever and means for movingthe jaws toward and trom each other to render them eiiective orineliective as desired.

Other objects and advantages of the invention will be apparent duringthe. course of the following description.

In the accompanying drawings forming a part of this specification and inwhich like numerals are employed to designate like parts throughout thesame:

Figure 1 is a side elevational view of a device constructed inaccordance with this invention showing the same attached 'to a rail,portions of the arm and operating handle being removed because of thelack ci drawing space.

Figure 2 is aY central vertical sectional view, with parts shown inelevation, taken substantially on the plane of the line 2-2 of Fig. 1.

In carrying out the invention I make use of a suitably shaped arm 1which is designed to have its upper end connected in any suitable waywith the car or other desired body to be locked or anchored. This armhas its lower end directed laterally as indicated at 2 to permit it tobear on the head of the rail R. By referring to the sectional view, itwill be seen that the laterally directed portion 2 is formed at oppositepoints with sockets and coiled springs 3 are arranged in these socketsand serve a purpose to be hereinafter set forth. Adjacent these sockets,the portion 2 of the arm is formed with a transverse hole and afbolt ais passed throughA this hole and extends beyond the opposite sides ofthe arm. To prevent rotation of the bolt, a screw 5 kis passed throughthe arm and' engaged with the bolt as clearly shown in I{`ig.,2.Associated with this bolt l are a pairof rail engaging jaws 6 which havetheir lowery ends bent inwardly toward each other as indicated at 7 topermit them to eiiectively engage the head of the rail@ Each of the jawsis provided nea-r its opposite ends with relatively large inclined holes8and 9 respectively. will be seen to permit the jaws to have free or`loose movement on the bolt le which extends through them.` It is to benoted that there are nuts 10 on the opposite ends of the bolt and thesenuts serve to force thexjaws toward one another to adjust them forproper engagement with different sized rails and to form fulcrums forthe jaws. As above pointed out, the aws are formed near their upper endswith holes 9 and another bolt 11 is passed through these holes. Thisbolt serves to connect the upper ends of the jaws together and to guidethem when these ends are moved with respect to each other and serves theadditional function of a ulcrum for the cam head 12 of the hand-operatedlocking lever 14. It is to be noted that the cam-head 12 is soconstructed as to permit the upper ends of the jaws to approach oneanother and in order to permit ythem to move very close together, theyhave their inner faces inclined as indicated at 15 to permit them toengage the central portion of the cam head as indicated in dotted linesinFig. 2. In order to permit the jaws to take this position, theopposite sides of the aforesaid laterally directed portion 2 of the armare bevelled as indicated at 16.

In use it will be seen that the jaws which were formerly held apart bymeans of the coiled spring 3 are fitted over the `head of the rail andthe hand lever 14 is then gripped and moved from the dotted lineposition indicated in Fig. 1 to the full line position and in so movingit, it binds theI laterally directed portion 2 ot the arm against therail head and rocks the jaws into engagement with the rail. Assumingthat the A By referring to these'holes, itv that they are sufficientlylarge f llO upper end or othery part ot the arin l is chained orotherwise connected with the car, it will be seen that the latter willbe anchored and preventedfroin moving along the track. By Ina-king useol this improved device, the car can be securely lockedto the rails onsteep inclines and even itl the brakes fail to hold, the car will stillbe locked againstnioveinent as will be seen. Any tendency of the car tonieve on the track will 'tend tocant` or tilt the jaws and cause theni`to obtain an even better grip than when truly vertical.

By carefully considering' the description in connection with thedrawings, persons 'tainiliar with devices of this class will doubtbeable to obtain a clear understanding' ot the invention. Therefore, ainore lengthy and vdetailed description. is deemed unnecessary.

Since probably the best results inay be obtained with the constructionand arrangement herein shown and described` this is taken asthe/preferred embodiment of the in vention. However, I wish it to beunderstood that ininor changes coming' within the scope of the subjoinedclaims may be resorted to it desired.

I claim:

l. .A car locking device comprising` an arm adapted to be connected witha car, the lower end of said arm being turned horizontally, a pair ofvertically elongated jaws on opposite sides of said laterally turnedarni ends, the lower ends ot said jaws being shaped togrip the ball ofthe rail, and a locking lever having` a wedge-like earnpivotally.InOuntedbet-ween the upper ends ot said jaws, whereby 'tospread said upper ends and rock said jaws around their pivotsvt'o'engage their lower ends with the rail.

2. A structure .as specified in claiin l, said jaws and said laterallyturned arm ends having relatively vertical inovenient, said wedge-likecani being` provided with a pe ripheral surface adapted to engage saidarm ends and force it intofengagenient with the rail when the lookinglever is operated.

3. A car locking` device comprising; an arm adapted to be connected witha car, the lower end of said arin being turned laterally and bevelled atit-s opposite side toward its upper edge, a bolt passing through saidarm end and extending` beyond the bevelled side thereof, a pair otvertically elongated jaws, rockably mounted on said bolt at saidbevelled sides, another bolt passing` loosely through the upper ends ofsaid jaws, and a locking lever having a wedge-like cani pivotallymounted on said v'lastlnained bolt for inverting' the upper ends ot saidjaws and rocking' the latter upon said first named bolt, whereby toengage the lower end ot said jaws with a rail.

In testimony whereof I have hereunto set niy hand.
